The number of devices available that support higher rates.
Every single DAC that SMSL (for example) produce, that has an optical input, accepts up to 192khz. I haven't bothered to look at other manufacturers. Every Wiim device outputs up to 192khz over optical.
Maybe 20 years ago there were few devices that supported higher rates.

One reason I bought an SMSL Sanskrit DAC for my bedroom setup (pairs with a Wiim Mini). It also has a USB input, so it worked with my phone, too.

This is one reason I went standalone DAC for my music listening. SMSL is affordable and the SU-1 and RAW MDA-1 can handle any stereo format you send them including DSD ripped from a SACD. I have been buying Blu-ray Audio and prefer to just rip the stereo tracks for ease of listening and those are frequently in 24/192.

I tried optical output into a two inexpensive DACs (Schiit Modi Multibit 2 and a Topping E30) and had no problem getting 192K. That said, I have heard that sometimes people have to try more than one optical cable to get to 192K, but the 4 cables I have -- all rather generic -- work fine at that speed.
 
The Ultra plays my DSD music from DLNA server and Tidal connect works well with both internal and external (USB out) DAC. I think most of these DACs will support DSD with USB input, not optical, as far as I know.

for music it works really well. TV is tricky since only AC3 support on ARC input. I tell Plex to transcode my DTS to AC3 and that works. all other movie streaming no problem.

Since the system is only 2.0, I am just wondering if the optical out from the TV would do just as good of a job as the TV ARC output? I only have 2) HDMI 2.1 ports and would like 2) streaming boxes on those, so thinking maybe optical out to Ultra. Only disadvantage might be the ultra not coming out of standby with optical?

I'll have to test it, I would imagine the AC3 decoder in Ultra will work with optical or ARC input?

Have you tried the USB out to your DACs? seems to work well.

No, I haven't. The optical example noted above was with my headphone setup in a different room. The Ultra is in my main system and I use its internal DAC/preamp into my power amp. Hope you don't mind that I don't feel like moving a bunch of gear around just to check the USB-out feature of the Ultra -- also haven't tried its phono/line inputs either. (I have used RPi USB out to other gear in the past. Have to confess that I don't hear a difference between USB/Coax/Optical when everything is set up correctly.)

This is good to know. I don't have a ton of ripped SACDs, but my one gripe with the Schitt Modi + is it won't play DSD files over USB. I use that with a headphone amp in one room and can't play those albums on it. WiiM Ultra supporting them is a plus though certainly not a must at its price point since few people have DSD files to play.

Yeah, Schiit doesn't support DSD, should be a way to convert to DoP (DSD over PCM) I think? that might be what is happening on mine anyway. as long as I can play them!

strange because I remember seeing 88/24 from my ripped SACDs (DSD64) once, now seems to be 192/24.

I'll check it when back from the islands.

It's all good, I don't think much difference it's just most DACs will support DSD only from USB input.

But the Wiim is converting any DSD content into PCM anyway right, so you don’t need a DAC that supports DSD.

Or have you found a way to get your DSD rips out of the Wiim untouched via DoP?

I ask as I haven’t :D

I'll have to mess with it when I get home, at some point I did see 88/24, and the Wiim screen said DSD., I see your point though!

I think I was just talking about DACs in general only supporting DSD from the USB input. If trying to pass native DSD through to external DAC, it would need DSD support it seems.
 
That’s why I need a streamer with no dac. Just digital out only is enough. And also included USB out.
 
Question : wiiamp can be the better in the world ... but the music its throuth ... the amp .. if you have bad amp or bad wire , its no good ?
 
Is there a way to add a crossover for a sub in the RME?

Yes, use the RCA outputs for the subwoofer and the XLR outputs for the main speakers. Most modern subs include a built-in crossover to handle the low-frequency cutoff. If not, use an external crossover or DSP device between the ADI-2 and your speakers/subwoofer for more advanced bass management. In most cases, your sub's built-in cross-over in conjunction with the RME "Loudness" control will provide your desired sound.
